liblzma: Fix handling of memlimit == 0 in lzma_index_decoder().
It returned LZMA_PROG_ERROR, which was done to avoid zero as the limit (because it's a special value elsewhere), but using LZMA_PROG_ERROR is simply inconvenient and can cause bugs. The fix/workaround is to treat 0 as if it were 1 byte. It's effectively the same thing. The only weird consequence is that then lzma_memlimit_get() will return 1 even when 0 was specified as the limit. This fixes a very rare corner case in xz --list where a specific memory usage limit and a multi-stream file could print the error message "Internal error (bug)" instead of saying that the memory usage limit is too low.
